Description

  Embodiments described herein relate generally to a machine roomless elevator.

  Japan's laws governing elevators have traditionally obliged to install emergency elevators when the building height and floor area exceed certain conditions. Emergency elevators are normally used for passengers and baggage, but they are used for fire extinguishing activities in the event of a fire or for rescue of passengers confined in a car room. .

  The emergency elevator is equipped with a car call back button and a primary fire / secondary fire changeover switch dedicated to the fire brigade so that the fire brigade can use the emergency elevator to facilitate fire fighting in the event of a fire. Yes.

  Conventionally, in this type of emergency elevator, it has been obliged to install a fireproof and waterproof machine room in the upper part of the hoistway, and to install an elevator control device and a hoisting machine in this machine room.

  This is because the emergency elevator is used for extinguishing fires in the event of a fire, so it is necessary to prevent water from entering the control device and the hoist due to water discharge. For this reason, the conventional emergency elevator was comprised as an elevator system which has a machine room (for example, refer patent document 1).

By the way, in recent years, machine roomless elevators in which a hoisting machine and a control device are arranged in a hoistway without providing a machine room in the upper part of the hoistway have been widespread. The rescue elevator could not be applied to the emergency elevator.
Recently, laws and regulations have been revised to allow the use of machine roomless elevators in emergency elevators under certain conditions (Ministry of Land, Infrastructure, Transport and Tourism Notification No. 1274).

  Furthermore, recently, restrictions on the arrangement of control devices have been further relaxed (Ministry of Land, Infrastructure, Transport and Tourism Notification No. 601 on June 2, 2017). According to this, when waterproofing of the drive unit and control unit exceeds the specified conditions (waterproofing that conforms to IPX2 stipulated in Japanese Industrial Standard C0920-2003, or equivalent or better), The drive unit and the control unit can be installed above the lower floor and below the uppermost floor.

  Here, it is assumed that when the fire brigade uses an emergency elevator to extinguish fire, the fire water that has been discharged enters the hoistway from the top floor landing floor. Is also designated to provide a drip-proof structure for the control device located below.

JP 2013-49565 A

  In the case of a machine roomless elevator where the control device is placed in the hoistway at a position lower than the floor surface of the top floor, even if the water discharged from the fire fighting activity is directly applied, a drip-proof structure is provided. Can maintain function. However, there is a problem in that the entire control device must have a drip-proof structure.

  On the other hand, disposing the entire control device at a position above the floor of the top floor is also an effective measure from the viewpoint of waterproofing, and in this case, a waterproof structure is not necessary.

  However, in the hoistway above the top floor, various devices are arranged in a narrow and limited space. On top of that, for example, a space for ascending / descending the counterweight, Therefore, it is necessary to secure a space necessary for the car-side sheave, which is often insufficient for arranging the entire control device.

  In addition, in order to be able to arrange the control device, there is a problem that the height (referred to as overhead) from the floor of the top floor to the ceiling of the hoistway must be increased.

  The present invention has been made in view of the above-described problems of the prior art, and does not require a large overhead and does not require a drip-proof structure for the entire control device. The purpose is to provide a machine roomless elevator that creates a rational layout that can arrange hoisting machines and all control devices in the road, and makes it possible to configure a machine roomless elevator as an emergency elevator.

  In the machine roomless elevator 100 shown in FIGS. 1 and 2, a pair of car-side guide rails 21 </ b> L and 21 </ b> R extending in the vertical direction are disposed on both the left and right sides of the car 20. The car 20 moves up and down in the hoistway 2 while being guided by the car side guide rails 21L and 21R.

  A pair of left and right weight side guide rails 23L and 23R are arranged on the back side of the car 20 so as to extend in the vertical direction. The counterweight 22 is guided by the weight side guide rails 23L and 23R and moves up and down in the hoistway 2. The machine roomless elevator 100 according to the present embodiment is a so-called rear fall type elevator in which the lifting / lowering track of the counterweight 22 is arranged on the back side of the car 20.

  A hoisting machine support beam 24 is bridged between the tops of the left car side guide rail 21L and the left weight side guide rail 23L. On the upper surface of the hoisting machine support beam 24, the hoisting machine 25 is placed and fixed. Further, the main sheave 26 of the hoisting machine 25 is positioned above the left end of the counterweight 22 toward the back side of the car 20. Further, the hoisting machine 25 and the main sheave 26 are coaxial, and their axes extend in parallel to the left side surface of the car 20.

  On the other hand, a lower beam 28 constituting a part of the car frame extends horizontally in the left-right direction below the car 20. As understood from FIGS. 1 and 2, a sheave support beam 29 extending in the front-rear and left-right directions in the horizontal plane so as to form an X shape with respect to the lower beam 28 is provided.

  On both ends of the sheave support beam 29, a pair of left and right car-side sheaves 30L and 30R are rotatably supported. These car-side sheaves 30L and 30R are arranged at positions symmetrical with respect to the center of gravity of the car 20, as can be understood from FIGS.

  A baffle sheave unit 50 including a pair of baffle sheaves 50a and 50b is provided below the hoisting machine support beam 24 and above the left car-side sheave 30L. In this embodiment, as shown in FIG. 2, the baffle sheave unit 50 has a baffle sheave base that extends rearward and downward from the center of the lower surface of the hoisting machine support beam 24 toward the left weight side guide rail 23L. 50c. At the lower end of the deflector sheave base 50c, one deflector sheave, that is, the first deflector sheave 50a, and at the upper end of the deflector sheave base 50c, the other deflector sheave, that is, the second deflector sheave 50b, is rotatable. It is supported.

Next, roping of the main rope 27 in the machine roomless elevator 100 according to the present embodiment will be described.
The main rope 27 will be described by dividing it into a portion where the car 20 is suspended and a portion where the counterweight 22 is suspended.

The part where the car 20 is suspended is roped as follows.
That is, the portion of the main rope 27 extending downward from the main sheave 26 is wound around the first deflecting sheave 50a, and then extends upward and wound around the second deflecting sheave 50b. Further, the main rope 27 extends downward from the second baffle sheave 50b, extends horizontally between the pair of left and right car sheaves 30L, 30R, and then extends upward from the right car sheave 30R to the right side. Locked to the hitch portion 31. In this way, the car 20 is suspended by 2: 1 roping.

On the other hand, the portion of the main rope 27 that suspends the counterweight 22 is roped as follows.
That is, a portion of the main rope 27 extending downward from the main sheave 26 toward the counterweight 22 is wound around the pair of left and right weight side sheaves 22a and 22b so as to extend horizontally, and further, the right weight side sheave 22b. After being wound around, it extends upward and is locked to the rear hitch portion 32.

  The rear hitch portion 32 is disposed on the upper surface of the support beam 33 spanned between the upper ends of the pair of left and right weight side guide rails 23L and 23R and in the vicinity of the upper end portion of the right weight side guide rail 23R. And is at the same height level as the hoist 25.

  The machine roomless elevator according to the present embodiment is used for transporting passengers and luggage during normal times. In the present embodiment, such an elevator is also used as an emergency elevator that can ensure fire-fighting operation even when a disaster such as a fire occurs.

  Here, FIG. 3 is a diagram showing the uppermost part of the hoistway. In FIG. 3, reference numeral 52 represents the top floor. The front-rear direction and the left-right direction are indicated by arrows.

  A hoisting machine support beam 24 is spanned between the upper ends of the left car side guide rail 21L and the left weight side guide rail 23L, and the hoisting machine 25 is installed on the upper surface of the hoisting machine support beam 24. Has been. Since both the car-side guide rail 21L and the weight-side guide rail 23L extend above the floor 52 on the uppermost floor and close to the ceiling, the hoisting machine 25 is installed at the height of the floor 52 on the uppermost floor. The position is considerably higher than the height.

In the machine roomless elevator according to the present embodiment, an elevator control panel (elevator control device) is arranged at the top of the hoistway as follows.
In FIG. 3, the elevator control panel performs a main circuit unit 60 that drives the hoist 25, a main control unit 70 that controls the operation of the entire elevator system during normal operation, and fire fighting operation control in the event of a fire. And an auxiliary control unit 80.

  The main circuit unit 60, the main control unit 70, and the auxiliary control unit 80 are attached to the right car-side guide rail 21R via brackets 34a to 34e. In the case of this embodiment, the main circuit unit 60, the main control unit 70, and the auxiliary control unit 80 are control panels having a vertically long casing, and extend in a straight line along the car-side guide rail 21R. Has been placed.

A regenerative resistance circuit unit 62 that converts the rotational energy of the motor of the hoist 25 into heat is provided at the upper part of the main circuit unit 60, and a plurality of heat dissipation holes are formed at the upper part of the front cover. Yes. The heat generated in the regenerative resistance circuit unit 62 is forcibly discharged to the outside by a built-in fan (not shown).
The lower end of the main circuit unit 60 is higher than the floor 52 on the top floor, and the upper end of the main circuit unit 60 extends to near the upper end of the car side guide rail 21R.

  Here, FIG. 4 is a plan view of the hoistway 2 from directly above. The main circuit unit 60 is disposed on the rear side of the car side guide rail 21R. The main control unit 70 and the auxiliary control unit 80 are both not shown in FIG. 4 because they have the same planar dimensions as the main circuit unit 60 and are arranged on the same vertical straight line below the main circuit unit 60. .

Next, the arrangement position of the main control unit 70 will be described with reference to FIG.
The main control unit 70 is arranged directly below the main circuit unit 60 without a gap. When a plane at the same level as the floor surface of the top floor is shown as the floor surface 52, the main control unit 70 is disposed at a position where the middle portion of the housing body is crossed by the floor surface 52. Therefore, the upper end portion of the main control unit 70 is at a position protruding above the floor surface 52, and the lower end portion is at a position below the floor surface 52.

Since such a main control unit 70 includes a portion lower than the floor 52 of the top floor landing, there is a possibility that the fire control water that has entered the hoistway will be covered during a fire fighting operation.
Therefore, the main control unit 70 has a drip-proof structure as shown in FIG.

  As shown in FIG. 5, in the main control unit 70, the housing body 71 is combined with the front cover 72 to form an elongated housing. On the left and right side surfaces of the housing main body 71, seal surfaces 75a and 75b bent at a right angle are formed in the longitudinal direction. Long strip-shaped seal members 74a and 74b are used so as to be attached to the seals 75a and 75b. Therefore, if the front cover 72 is fixed to the housing main body 71 so as to sandwich the seal members 74a and 74b, the main control unit 70 can be simply constructed as a drip-proof structure.

Next, in the machine roomless elevator according to the present embodiment, in addition to the main control unit 70 as described above, an auxiliary control unit 80 for controlling the fire fighting operation of the elevator in an emergency is arranged as follows.
As shown in FIG. 3, the auxiliary control unit 80 is attached to the right weight side guide rail 23R via brackets 34d and 34e. The auxiliary control unit 80 is disposed immediately below the main control unit 70 at a predetermined interval.

The whole auxiliary control unit 80 is below the floor 52 on the top floor. Therefore, the auxiliary control unit 80 has a drip-proof structure as shown in FIG.
Similarly to the main control unit 60, the auxiliary control unit 80 is combined with the front cover 82 to form an elongated case. On the left and right side surfaces of the housing body 81, seal surfaces 85a and 85b bent at a right angle are formed. Long band-like seal members 84a and 84b are used so as to be attached to the seal surfaces 85a and 85b. Therefore, if the front cover 82 is fixed to the housing main body 81 with the seal members 84a and 84b interposed therebetween, the auxiliary control unit 80 can be simply constructed as a drip-proof structure.

  The upper end of the auxiliary control unit 80 is closed by a top cover 86. The top cover 86 is set larger than the size of the cross section of the housing body 81, and the top cover 86 has a hook-shaped drip-proof structure that projects in the left-right direction and the front-rear direction.

Next, FIG. 7 is a diagram schematically showing the arrangement and wiring status of the elevator control device in the present embodiment.
The main control unit 70 and the auxiliary control unit 80 disposed below the main control unit 70 are connected to each other by outside panel wiring. The main control unit 70 and the auxiliary control unit 80 are connected to each other by a tail cord as well as being connected by outside panel wiring. The auxiliary control unit 80 is usually equipped with an emergency call switch 87, a monitoring panel emergency call switch 89, a primary firefighting operation / secondary firefighting operation changeover switch 90, and a panel installed at predetermined reference floors such as the first floor and the evacuation floor. Connected by external wiring.

  When the emergency call switches 87 and 89 are turned on, the elevator is switched from the normal operation by the main control unit 70 to the primary firefighting operation by the auxiliary control unit 80. In this primary fire fighting operation, the landing call and car call registered at that time are canceled and the car is driven directly to the floor where the emergency call switch 87 is located. When the primary fire fighting operation is switched to the secondary fire fighting operation, the detection of the opening of the landing door or the car door becomes invalid, and the driving with the landing door or the car door being opened becomes possible. This allows firefighters to perform firefighting activities on the car.

Next, in FIG. 3, the transformer 55 is disposed via a bracket 45 installed on the upper ends of the weight side guide rails 23L and 23R. The transformer 55 is located below the installation height of the hoist 25, but is much higher than the floor 52 on the top floor. In this embodiment, the transformer 55 is a transformer having a flat body and is installed horizontally so as not to affect the overhead. The upper surface of the transformer 55 is located below the lower surface of the hoisting machine 25.
There are various ways of attaching the transformer 44. For example, the transformer 44 may be attached to a vertical column extending along the back wall of the hoistway 2 via a bracket, or may be attached to a bracket fixed by hitting an anchor on the back wall.

  2 to 4, reference numeral 54 indicates a governor. The governor is disposed obliquely below and forward of the hoist 25.

Next, the effect of the machine roomless elevator according to the present embodiment will be described.
In the machine roomless elevator according to the present embodiment, as shown in FIGS. 3, 4, and 7, the auxiliary control unit 80, the main control unit 70, and the main circuit unit 60 are arranged in this order from the bottom. Only the auxiliary control unit 80 below the floor 52 of the top floor and the main control unit 70 partially below the floor have a drip-proof structure.

  When a fire occurs, the operation of the elevator is switched to firefighting operation and controlled by the auxiliary control unit 80 to function as an emergency elevator used by the fire brigade. There is a possibility that the fire extinguishing activity may also be performed on the top floor, and water for fire extinguishing may enter the hoistway from the landing on the top floor.

  In this embodiment, since the auxiliary control unit 80 and the main control unit 70 are protected from water wetting by the drip-proof structure, the function as an emergency elevator can be reliably maintained while being a machine roomless elevator. . The waterproof structure of the auxiliary control unit 80 and the main control unit 70 is a simple structure, but exhibits waterproof performance against water from any of the front, back, and side directions.

  Since the hoist 25 and the main circuit unit 60 are above the floor 52 on the top floor, a drip-proof structure is unnecessary. It can be said that the regenerative resistance circuit portion 62 of the main circuit unit 60 does not conform to the drip-proof structure because of the heat release hole, but rather has no drip-proof structure. Further, since the main circuit unit 60 does not get wet, when a fire is extinguished and the normal operation is restored, trouble such as a failure can be avoided in advance, so that early restoration is possible.

  On the other hand, the arrangement as described above enables the auxiliary control unit 80, the main control unit 70, and the main circuit unit 60 to be installed in this order from the bottom without increasing the overhead at the top of the hoistway.

In FIG. 7, in the hoistway with a large overhead on the top floor of the hoistway, there is a margin in the overhead. Therefore, even if the main control unit 70 is placed at a high position in relation to the floor surface 52 on the top floor, the main circuit The unit 60 can be installed without hitting the ceiling of the hoistway.
On the other hand, in a hoistway with no margin for overhead, if the position of the main control unit 70 is lowered relative to the floor surface 52 on the top floor, the main circuit unit 60 can be moved without increasing the overhead. Can be installed. Thus, it can respond flexibly according to the structure situation of the uppermost part of the hoistway.

  In FIG. 3, since the transformer 55 is arranged on the top of the car guide rails 23L and 23R, the water supply is not affected without affecting the arrangement of the auxiliary control unit 80, the main control unit 70, and the main circuit unit 60. It can be placed in a position where it does not get wet.

  Moreover, even if the counterweight 22 is a rear drop type machine roomless elevator as in this embodiment, it is not necessary to increase the effective dimension of the hoistway 2 and without interfering with the counterweight 22. The space necessary for disposing the main circuit unit 60, the main control unit 70, and the auxiliary control unit 80 on the back side of the car 20 can be secured.

  Further, as shown in FIG. 4, the arrangement of the counterweight 22, the hoisting machine 25, and the deflecting sheaves 50a, 50b can be optimized, so that the main circuit unit 60, the main control unit 70, the auxiliary control unit 80 As a result, the machine room-less elevator system does not hinder the roping of the main rope 27.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS.
FIG. 8 shows an arrangement (modification 1) of the main circuit unit 60, the main control unit 70, and the auxiliary control unit 80 according to the second embodiment.

  In the first modification, the auxiliary control unit 80 is disposed in a region extending up and down with respect to the floor surface 52 on the uppermost floor, and a plane including the floor surface 52 crosses the auxiliary control unit 80. In this case, the auxiliary control unit 80 has a drip-proof structure shown in FIG. Since the main circuit unit 60 and the main control unit 70 are arranged above the floor 52 on the top floor, they are not provided with a drip-proof structure.

  FIG. 9 shows an arrangement (modification 2) of the main circuit unit 60, the main control unit 70, and the auxiliary control unit 80 according to the second embodiment.

  In the second modification, among the main circuit unit 60, the main control unit 70, and the auxiliary control unit 80, the main circuit unit 60 is arranged such that a plane including the floor 52 crosses. In this case, the drip-proof structure shown in FIGS. 5 and 6 is applied to the auxiliary control unit 80 and the main control unit 70 below the floor 52, respectively, as in the first embodiment. As for the main circuit unit 60, the portion of the regenerative resistance circuit portion 62 is not preferred to have a drip-proof structure, so if it is placed above the floor 52 on the top floor and the remaining portion has a drip-proof structure, Good.

  Even with the arrangements as in the first and second modifications, the main circuit unit 60 main control unit 70 and the auxiliary control unit 80 can be installed without increasing overhead, as in the first embodiment.
